That should really be updated IMO.  Also, the comment on Xen is specific
to XenServer.  Upstream xen.org works fine as an OpenStack compute node
- and it is not necessary to run it in a VM :).

No.  With the ImagePropertiesFilter, you can set properties on your
images to ensure the scheduler places instances based off those images
on correct compute nodes.  E.g.

glance image-update --property architecture=x86_64 --property
hypervisor_type=xen --property vm_mode=xen <img>
